Geranium plant named ‘Kleflasal’

ABSTRACT

A new and distinct cultivar of Geranium plant named ‘Kleflasal’, characterized by its upright and rounded growth habit; freely basal branching habit; star-shaped green-colored leaves with darker green zonation pattern; and star-shaped pink-colored single flowers.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Pelagaronium×hortorum cultivar Kleflasal.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium×hortorum, and hereinafter referred to by the name ‘Kleflasal’.

The new Geranium is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program was to develop new Geraniums with unique flower forms, freely-branching growth habit and interesting flower and foliage colors.

The new Geranium originated from a cross made by the Inventor in July, 1996 of the Pelargonium×hortorum cultivar Gemini, disclosed in U.S. Plant Pat. No. 5,980, as the female, or seed, parent with an unidentified proprietary selection of Pelargonium×hortorum, not patented, as the male, or pollen, parent. The cultivar Kleflasal was discovered and selected by the Inventor as a flowering plant within the progeny from this cross in a controlled environment in Stuttgart, Germany, in June, 1997.

Asexual reproduction of the new cultivar by terminal cuttings taken at Stuttgart, Germany, since July, 1997 has shown that the unique features of this new Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kleflasal’. These characteristics in combination distinguish ‘Kleflasal’ as a new cultivar and distinguish it from other known Geranium cultivars:

1. Upright and rounded growth habit.

2. Freely basal branching habit.

3. Star-shaped green-colored leaves with darker green zonation pattern.

4. Star-shaped pink-colored single flowers.

Plants of the new Geranium differ primarily from plants of the cultivar Gemini in flower color. In addition, in side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Geranium are stronger and more vigorous than plants of the cultivar Gemini. Plants of the new Geranium differ primarily from plants of the male selection in leaf and petal shape.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a side perspective view of a typical flowering plant of ‘Kleflasal’ that was grown for about three months in a 12-cm container. Flower and foliage colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Geranium.

DETAILED BOTANICAL DESCRIPTION

The cultivar Kleflasal has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants that were planted in January in 12-cm pots in Stuttgart, Germany, and grown for about three months under commercial practice in a glass-covered greenhouse with day temperatures about 18 to 22° C., night temperatures about 15 to 18° C. and light levels about 20,000 to 50,000 lux. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
